On Thursday nights, the yarn comes out. Every week, my fellow entomology graduate students and I get together to make insect-inspired crafts. One crochets butterflies, another makes earrings out of wings from discarded research specimens, and a third decoupages notebooks with figures and illustrations from journal articles thrown out after a lab cleanup. It may sound light or frivolous, but it's far from it. A regular social night like this-whether built around crafts or some other shared interest-can make a significant difference in our work and our lives.
